ABSTRACT

A drinking vessel configured for a removable engagement with the capped end of a bottle through engagement with the bottle or the cap. The device features a fluid cavity separated from a base cavity by a central wall, which is configured for drinking or pouring a measured amount of liquid therefrom. The device is engageable to the bottle or cap by insertion of the cap end of the bottle, into a cavity in the base end, and exerting force along an axial line running through the bottle. A frictional engagement between surfaces of the device and the bottle is achieved which may be enhanced by biasing components.

This application claims the benefit or U.S. Provisional PatentApplication Ser. No. 61/486,680, filed May 16, 2011, and incorporatedherein in its entirety by reference. The present invention relates todrinking vessels.

BACKGROUND OF THE INVENTION

1. Field of the Invention

More particularly, it relates to a drinking or measuring glass which isconfigured for a removable engagement with the capped end of a bottle.

2. Prior Art

In the fast paced world of bartending and nightclubs, it is wells knownthat faster service breeds happier customers and that happier customerstend to leave better tips for the serving staff. Measuring of the pourof alcohol to mixer is the most time consuming portion of providingcocktail service, and can be inhibited by the lack of a measuring vesselfor the alcohol portion.

Individuals attending a party or picnic have the same needs for makingmixed cocktails, if not an enhanced need since a non professional isgenerally unable to estimate a proper pour measurement for the alcoholicportion of a mixed drink. Additionally, for the more refined alcoholconsuming individuals who enjoy aged or fine liquor, adding such to amixer may not be their choice of use. However, such users frequentlychoose to sip a fine alcoholic beverage slowly either straight up or inmeasured amounts on ice. Additionally, it is well known that collegestudents have a proclivity to inbibe which can require the employment ofa measured drinking vessel being handy from which to pour and measurebefore drinking from the glass.

As a consequence, from professionals to social drinkers, there is acontinual need for the easy acquisition of a measured drinking ormeasuring vessel such as what is conventionally termed a shot glass.This one vessel allows bartenders and amateurs to properly mix thedesired ratio of alcohol to mixer, and to simply empty the shot glassshould direct consumption in a measured amount be desirable.

Additionally, in any given bar or adult nightclub, one canconventionally find measured drinking vessels such as pint glasses, wineglasses, the occasional champagne flute, and of course, the frequentlyrequested shot glass. Since shot glasses are conventionally small,holding only about 1 ounce to 1.5 ounces of fluid, bartenders andpatrons of the like are continually in need of having such shot glassesreadily available for both measuring and for direct employment indrinking measured amounts of liquid.

Prior art has shown many attempts to provide shot glasses which doubleas or are part of the bottle cap for a bottle or the like. US. Pat. App.Pub. 2008/0011710 A1 to Cohn and US. Pat. App. Pub. 2008/0116164 A1 toDellinger et. al. teach a combined shot glass and bottle cap. The shotglass of Cohn includes a threaded base portion adapted for watertightengagement with the often threaded top of a liquor bottle whileDellinger includes a threaded portion located at the inside top lip areaof the shot glass.

However, given the wide variety of manufacturers of liquor and bottleswith many having slightly different diameters and different threads, thethreaded portions of Cohn and Dellinger are not easily employed evenwith bottles which may be virtually equal in size. This is because thethreads of the prior art would need to be formed to vary according tothis wide variety of conventional bottles and caps and threads and theresulting costs for manufacture and distribution required to accommodatethis plethora of threaded engagements and bottle types. Further, becausea threaded engagement normally takes a bit of time to rotationallyengage mating threaded surfaces, users are liable to not employ suchdevices in the busy confines of a bar or at a lively party.

Furthermore, the threads of Cohn are located on the base of the actualliquid holding portion of the shot glass, which in use is employed as auser drinking vessel. Threading the bottle into the same space occupiedby what a user drinks, can expose the contents of the body to thepathogens known to inhabit the human mouth if the device is not washedfirst which is highly possible. To subsequently replace this cap as abottle cap is at best unsanitary. In addition, as noted, providingthreads as a means for engagement to a bottle requires a bartender toconstantly thread and unthread a shot glass as needed, and as notedabove, taking longer by doing this task runs the risk of reducingpossible earned tips.

As such there is a continuing and unmet need for a measured volumedrinking vessel such as a shot glass or similar drinking vessel, whichis configured to provide quick, easy, and sanitary removable engagement,with the bottle from which the user intends to measure or drink. Such adevice should be configured for easy and quick engagement anddisengagement to a wide variety of bottles or bottle caps to allowwidespread use. Such a device should be configured to keep germs andpathogens from the user's mouth and face, separated from the contents ofthe bottle when the device is reattached. Such a device should be easyto mount and dismount from its bottle mounting but still provide asecure mount and in some instances a sealed engagement with the bottleitself.

SUMMARY OF THE INVENTION

The device herein disclosed and described provides a solution to theshortcomings in prior art and achieves the above noted goals through theprovision of a measured volume drinking and measuring vessel, shown anddescribed as a shot glass. The shot glass is configured for universalremovable engagement over a bottle cap and engaged therewith to theunderlying bottle.

In the particularly preferred modes, the disclosed device includes acylindrical body having a measured fluid vessel portion physicallyseparated from a formed base portion at the opposite end of a centrallylocated wall. The base portion, so separated, inhibits pathogens fromgetting into the bottle and has a formed means for removable engagementto a bottle or cap as part of the cylindrical body.

In all modes of the device, the fluid vessel portion typically resemblesand is dimensioned as a shot glass as is conventionally known in theart. The base portion generally includes a circular recess defined by asurrounding sidewall and means for engagement for maintaining the devicein an engaged position to the top of a bottle cap or the cappablebottle. The biasing of the frictional engagement may be provided by acircumferential protrusion disposed within the circular recess of thebase or one or a plurality of similarly disposed compressible butrebounding O-rings, both of which provide a means for snap over fit typeengagement. Alternatively, flexible members having projections and/orsecondary thread engaging projections provide means for engagement tothe bottle or cap.

It is an advantage of this and other modes of the present invention toprovide a “snap on” means for quick removable engagement to a bottle orcap in that it provides quick and easy operation to encourage use. Suchan engagement requires no rotational thread engagement and separates andrejoins with the force exerted axially by the user's grip of the device.

Additionally, the engagement between the bottle and the device maintainsseparation from the drinking end of the device and the bottle threads,and as such it does not come into direct contact with the threadedportion of a bottle which can risk contaminating the enclosed liquorwith pathogens from surfaces on which such a device sits. Furthermore,in all modes of the device, the original screw on or compressed cap canremain on the liquor bottle as intended by the manufacturer.

In another particularly preferred mode biased frictional engagementbetween the device and the bottle or cap, can be maintained using arebound type biasing means such as opposing flexible members,protrusions or O-ring disposed within the circular recess of the baseportion which are configured in pitch and projection to optionallyprovide a means to engage to the threads of a bottle or projections fromthe exterior of the bottle surface. In this mode, the device is alsoemployable to replace a lost or otherwise unwanted bottle cap.

In yet another particularly preferred mode the device includes auniversal bottle cap that is designed for removable engagement with thedevice. The universal bottle cap simply replaces the existing bottle capof the liquor bottle and is specifically purposed for removableengagement with the device.

With respect to the above description, before explaining at least onepreferred embodiment of the herein disclosed invention in detail, it isto be understood that the invention is not limited in its application tothe details of construction and to the arrangement of the components inthe following description or illustrated in the drawings. The inventionherein described is capable of other embodiments and of being practicedand carried out in various ways which will be obvious to those skilledin the art. Also, it is to be understood that the phraseology andterminology employed herein are for the purpose of description andshould not be regarded as limiting.

As such, those skilled in the art will appreciate that the conceptionupon which this disclosure is based may readily be utilized as a basisfor designing of other structures, methods and systems for carrying outthe several purposes of the present disclosed drinking vessel device. Itis important, therefore, that the claims be regarded as including suchequivalent construction and methodology insofar as they do not departfrom the spirit and scope of the present invention.

As used in the claims to describe the various inventive aspects andembodiments, “comprising” means including, but not limited to, whateverfollows the word “comprising”. Thus, use of the term “comprising”indicates that the listed elements are required or mandatory, but thatother elements are optional and mayor may not be present. By “consistingof’ is meant including, and limited to, whatever follows the phrase“consisting of”. Thus, the phrase “consisting of” indicates that thelisted elements are required or mandatory, and that no other elementsmay be present. By “consisting essentially of” is meant including anyelements listed after the phrase, and limited to other elements that donot interfere with or contribute to the activity or action specified inthe disclosure for the listed elements. Thus, the phrase “consistingessentially of” indicates that the listed elements are required ormandatory, but that other elements are optional and mayor may not bepresent depending upon whether or not they affect the activity or actionof the listed elements.

It is an object of the invention to provide a measuring vessel such as ashot glass which is configured in an easily removed engagement to abottle or cap that is sanitary, easy to use, and cost effective inmanufacture.

It is another object of the invention to provide a drinking vessel suchas a shot glass with means for removable engagement which employs anaxial force engageable and removable snap fit style engagement such asprovided by O-rings, opposing flexible members, or similar means forbiased frictional engagement with bottle threads or protrusions.

It is yet another object of the invention to provide a means forremovable engagement including an O-ring or similar means for impartingbiased frictional engagement disposed at a pitch angle for optionaloperative engagement with a threaded portion of a bottle.

It is still another object of the invention to provide a universalbottle cap that is specially designed for engagement with the shot glassof the present invention.

Yet another object is the provision of a shot class type measuring anddrinking vessel, which is adapted for easy engagement over the cap of abottle, with the exterior of the bottle neck using flexible memberswhich allow for easy axial force directed engagement and securement andwhich may optionally seal the bottle when so engaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Now referring to drawings in FIGS. 1-18, wherein similar components areidentified by like reference numerals, there is seen in FIG. 1 anelevated view of the shot glass device 10 of the present invention. Inall favored modes of the device 10 it includes a fluid vessel portion 12and a base portion 16 which is configured for removable engagement withthe cap end of a bottle 25, particularly a liquor bottle 25 for whichmeasurement vessels are employed for mixology.

The fluid vessel portion 12 is defined by a cavity 14 formed by asidewall extending from a central wall 13 to a lip 15. In a particularlypreferred mode the cavity 14 holds 1 to 1.5 ounces of fluid. However,those skilled in the art will appreciate that the device 10 is capableof various size modifications to hold any amount of fluid and isanticipated in this disclosure. The device 10 may be formed of polymericmaterial or metal or in some cases glass, or material of the like knownin the art for formation of measuring vessels such as shot glasses andsimilar devices. Furthermore, the device 10 can be manufactured usingconventional manufacturing techniques known in the art.

FIG. 2 shows a cross sectional view of a mode of the device 10 betterdepicting a first mode of the base portion 16 which provides a means forremovable engagement with a conventional bottle cap 29 (FIG. 14) orbottle 25 neck, via a biased frictional engagement. In all modes thebase portion 16 generally includes a circular recessed cavity 18 definedby an interior wall surface 17 of a surrounding sidewall 23. In oneparticularly preferred mode, the device 10 includes a protrusion 20annular or in multiple positions around the circumference of the cavity18, which is formed by a projection of the interior wall surface 17 ofthe cavity 18 as depicted in FIG. 2. The protrusion 20 is particularlypreferred to be formed as a unitary structure with both the base 16 andvessel 12 portion of the device yielding a device 10 formed in a unitarystructure.

In use, the device 10 in all modes, may be placed over the top of acapped or uncapped bottle 25 and maintained in an engaged state, using acooperative removable engagement with the bottle neck or cap 29, withinthe cavity 18 of the base portion 16. The protrusion 20 provides a meansfor frictional engagement with the exterior circumference of a bottlecap 29 in a snap fit type engagement where the bottle cap 29circumference is at least equal to the circumference of the peak of theprotrusion 20. Such bottle caps 21 are conventionally aluminum orplastic and will deform to accommodate the frictional engagement of theprotrusion 20 surface, which may engage the cap 29 circumference, orjust below a lower edge of the cap 29. The device 10 in this mode,provides a quick, convenient, and flashy means to store a shot glasswithout the need for a threaded engagement which can take a long time toengage due to the multiple rotations required to engage mating threads.

In another particularly preferred mode as shown in FIG. 3 the cavity 18within the base 16 of the device 10 further includes a first 22 andsecond 24 annular protrusion disposed on the interior wall surface 17 asa means for biased frictional engagement. This mode provides a means foradded securement when engaged to a bottle cap in the as used mode asdescribed. Shown in FIG. 4 is yet another particularly preferred mode ofthe device 10 in which the cavity 18 of the base portion 16 includes anannular recess 26 on the interior wall surface 17 in which an O-ring 28is operatively engaged within. This mode further provides a means forremovable biased frictional engagement with a bottle cap and may providea tighter fit to a bottle cap given the compression and reboundflexibility of a typical O-ring 28. Additionally, due to wear that mayoccur from repetitive use it may be more advantageous to have areplaceable O-ring 28 as opposed to the unitary structure of the modedescribed in FIGS. 1 and 2.

The O-ring 28 style means for removable engagement is shown in anotherparticularly preferred mode in FIG. 5. This mode employs a first annularcavity 30 and a second annular cavity 32 within the interior wallsurface 17 of the base cavity 18. A first 34 and second 36 O-ring 28 areshown as operatively engaged within.

Further particularly preferred modes are shown in FIG. 6 and FIG. 7.There is seen in FIG. 6 an annular cavity 38 within the interior wallsurface 17 that is adapted to engage a concave cross section O-ring 40.In use upon engagement with a bottle cap it is preferred that theconcave wall of the O-ring 40 engages the exterior of the surface of thebottle cap 29 shown in FIG. 14 for instance. In this manner theconcavity can create a suctional engagement providing added security.FIG. 7 shows a first annular cavity 42 and a second annular cavity 44within the interior surface 17 of the base cavity 18. Similarly employedare a first O-ring 46 and a second O-ring 48.

FIG. 8 shows still further preferred mode of the device 10 wherein theannular cavity 50 and O-ring 52 are disposed at a pitch angle, α 54,relative the horizontal top surface of the bottle. Such pitch angle 54is provided to employ the device 10 and provide means for a threadedengagement with threads 58 conventionally located atop a screw on cappedbottle. In this mode the device 10 doubles as the actual bottle cap. Thepitch angle 54 as such corresponds to the pitch angle of the threadedbottle top to provide secure engagement. It must be noted that theprovision of a pitch angle 54 may be employed on any of the modespreviously disclosed and is not limited to the O-ring style biasingmeans as depicted in the figure.

There is seen in FIG. 9 another preferred mode of the device 10 having acomplimentary bottle cap 11. The bottle cap 11 is of generally the samestyle and construction of liquor bottle caps known in the art althoughfurther including a annular recessed cavity 56 about the outer surface55. The annular cavity 56 is employed for cooperative engagement with acompressible annular ring such as an O-ring which forms a means forbiased engagement within the base cavity 18 of the shot glass device 10of the present invention. A cross sectional view is shown in FIG. 10showing the cap 11 having a threaded 58 interior, prior to cooperativeengagement within the cavity 18 of the base portion 16 of the device 10.It must again be noted that the bottle cap 11 can be employed with anyof the modes previously disclosed upon simple modifications that wouldbe obvious to a person skilled in the art, and should not be consideredlimiting by the depiction in the figure.

FIG. 11 depicts the device 10 and cap 11 operatively engaged wherein theO-ring 28 is seated within the recess cavity 56 of the cap 11.

A still further mode of the device 10 is shown in FIG. 12. In this modethe means for biased frictional engagement with a bottle cap 29 (FIG.12) is employed within the cavity 14 of the fluid vessel portion 12. Thedevice 10 in this mode the device provides a means for removableengagement to a liquor bottle 25 wherein the device 10 is inverted andengaged to a bottle cap such as that in FIG. 13 or FIG. 14.

As in FIG. 12 the cavity 14 employs an annular recess 26 on the interiorwall surface 19 in which an O-ring 28 is operatively engaged within. Itmust be noted, however, that the employment of a means for biasedfrictional engagement within the cavity 14 of the drinking vessel 12 canbe any of those particularly preferred means for removable engagementpreciously disclosed in FIGS. 2-8 and should not be considered limitingby the depiction.

As shown in FIG. 13 a cooperative bottle cap 11 is in operativeengagement with the device 10. However, the device 10 in this mode maysimilarly be operatively engaged to any existing bottle 25 or bottle cap29 (FIG. 14) as noted with the previous preferred modes, while theengagement with the preferred bottle cap 11 is shown merely fordemonstrative purposes.

It is further noted that the mode of the device 10 shown in FIGS. 12 and13 may be employed in combination with any of the modes of the device 10in FIGS. 2-8 wherein a means for removable engagement to a bottle cap isalso disposed within the cavity 18 of the base portion 16. In thismanner the employment of the device 10 will be user determined, i.e.removable engagement with either the base portion 16 or the vesselportion 12.

FIG. 14 depicts another particularly favored mode of the device 10herein having a plurality of raised surfaces 61 at distal ends offlexible members 63 formed by voids in the sidewall 23 which impart abiasing force, toward an inserted bottle 25 or cap 29 for an enhancedfrictional engagement to the exterior of the bottle 25, or the cap 29depending on their number and location. As shown, the raised surfaces 61form a projection at a position configured to provide a means to engagethe bottle 25 itself either adjacent to the cap 29 or on the oppositeside of an annual stop ring 67 or the exterior threads 58 provided withconventional bottles 25 for such caps. As can be seen the number andposition of the raised surfaces 61 may be changed to deflect theflexible members 63 away from the bottle 25 which causes the inward biasand increased frictional or mechanical engagement of the flexiblemembers and raised surfaces 61.

However, the device 10 is still easily engaged by a simple sliding ofthe cavity 18 axially upon the capped end of the bottle 25 since theflexible members 63 and attached raised surfaces 61 will deflect awayfrom any engagement to the bottle or cap while force is applied in theaxial direction of the bottle. Thereafter, the flexible members 63impart biased force in the direction of the axis of the bottle 25 andupon the contacts between the raised surfaces 61 and their contacts withthe exterior of the bottle 25. An increase in the thickness of theraised surfaces 61 provides a means to increase biasing pressure whereasthinning it will decrease biasing pressure if desired.

As shown in FIG. 14, one preferred mode of the device 10 places theraised surfaces 61 in positions to override an annular ring 67conventionally employed on many liquor bottles 25 during the axialtranslation which occurs while the user engages the device 10. Thus, theraised surfaces 61 override the annular ring 67 by a flexing of theflexible members 63 during engagement and thereafter provide means forengagement of the device 10 to the bottle 25 which is especially strong.This mode of engagement works well if the device 10 is employed as thecap and if a seal 71 is provided as shown in FIG. 14 b, the engagementof the raised surfaces 61 against the side surface of the annular ring67 is sufficiently strong to hold the seal 71 compressed and sandwichedbetween the sidewall 23 and the top edge of the bottle 25.

FIG. 14 b depicts a particularly favored mode of the device 10 which mayemploy the engagement capabilities of that of FIG. 14 or 17, but whichalso may employ two or more slidably engageable projections 80 whichwill engage with the threads 58 of the bottle 25 and allow the device 10to function as a sealed cap. Preferably a first surface 81 is angled toform a ramp, whereby the bottle edge 83 and the threads 58 will slidethereon and deflect the flexible members 63 during a forced axialtranslation of the device 10 by a user sliding upon the end of thebottle 25. Once that force ceases, the projections 80 are positioned toengage within the gaps forming the threads 58. This engagement of theprojections 80 within the recesses or gaps of threads or ifappropriately positioned, on the opposite side of the projecting annularring 67 from the cap end of the bottle 25 provides an especially secureengagement which is not easily removed by dropping or bumping. Removalis accomplished by exerting sufficient force in an axial direction awayfrom the bottom of the bottle 25 and toward the cap end, to deflect theflexible members 63, or by rotating the device 10 to allow theprojections 80 to follow the threads 58 and unscrew or loosen it fromthe bottle 25.

The device 10 may employ the projections 80 in place of the raisedsurfaces 61 to engage either or both of the threads 58 and the annularring 67. The projections 80 may also be employed with shorter flexiblemembers 63 so as to engage with the threads 58 of the bottle 25. A moreuniversally engageable device is provided by providing flexible members63 with either the projections 80 at the distal end to engage a ring 67and positioned to engage the threads 58 or with projections positionedto engage the threads 58 and the raised surfaces 61 positioned to engagea ring 67. In this fashion should the ring 67 not be present, atranslatable engagement of the threads 58 is still achievable, and ifthe ring 67 is present, the projections translatabley engage with thethreads 58 and a second engagement is achieved with the side of the ring67. A seal 71 in any of the modes of the device of FIGS. 14 and 14 benhances its ability in that it may also function as a sealed lid shouldthe cap be lost or need replacing.

FIGS. 15 and 16 show a perspective view of the device 10 and the cavity18 flexible members 63 defined by gaps 85 formed in the sidewall 23which is formed of a flexible material such as a polymeric material orthin metal. As noted the flexible members 63 will deflect when axialforce in a direction from the cap engageable end of the bottle towardits bottom end is applied by the user with the capped end within thecavity 18. Thus, an easy and fast means for engagement usingtranslational movement is provided which encourages use and helpsprevent losing the device. As noted the projections 80 may be used inlieu of the raised surfaces 61 or in combination therewith.

FIG. 17 is a side view of a dismounted mode of the device 10 asdescribed and enlarged to aid in depiction of structure. The flexiblemembers 63 are shown as are the gaps 85 formed in the sidewall 23defining them. The raised surface 61 is positioned upon the flexiblemembers 63 so as to engage with the annular ring. Of course theconfiguration of FIG. 14 b is also employable substituting or includingthe projections 80 in place of or in combination with the raisedsurfaces 61. FIG. 18 is a sectional view of the device of FIG. 17, takenalong line 18-18 and showing the components of the device 10.
